Hol Chan Marine Reserve is located off the southern tip of Ambergris Caye. Hol Chan Marine Reserve is doubtfully one of the most popular dive sites in the Caribbean, and indeed in Belize and has burgeoned into a unique refuge, with vigorous coral formations and a richness of marine life. The entire reserve focuses on a cut through the reef (called a quebrada) which is little more than 25 yards wide and 30 feet deep about 4 miles southeast of San Pedro. The tour will then head to the neighbouring Shark Ray Alley, where you will snorkel or dive and view ecstatic Nurse Sharks and Southern Sting Rays. When you arrive, you will see the surface often boiling with rolling sharks and stingray as they compete for the scraps. These creatures have a great tolerance for spectators.
